Bezosis blasting off from land he owns in West Texas;Virgin Group founder Richard Branson plans to launch tourists from southern New Mexico as early as next year; and Musk is planning an eventual new SpaceX launchpad in extreme southern Texas, near South Padre Island. While this trio of space tycoons currently dominate the nascent industry, more companies will soon join the party. And the potential for what may eventually be daily launchescarries major implications for air travel.

“Commercial space launch needs to be better integrated into the national airspace,” noted Caryn Schenewerk, Hawthorne, Calif.-basedSpaceX’s senior counsel and director of government affairs.The Falcon 9 exceeds 60,000 feet on launch “in a quick 90 seconds,” with its reusable rocket boosters only requiring use of the airspace for one minute before landing.

Tim Canollis president of ALPA, theunion which represents 60,000 U.S. and Canadian pilots. Hecautions that work is needed to make the two industries operate seamlessly, sayingTuesday at a
hearing
of a House
Transportation and Infrastructure subcommittee in Washington
that FAA operations don’t have “real-time data” on rockets’ movements. Both industries need to learn more about each other during any federal rulemaking process, he said.

The U.S. licensed only 23 commercial launches last year, but that’s likely to increase.As the launch industry matures, the ultimate goal is to incorporate spacecraft into the routine flow of the 42,000 daily aircraft that the FAA controls, making a SpaceX Falcon 9 bound for the International Space Station no different than an American A321 headed to Miami. “The next step,” said Canoll,is to put space travel and air travel together, so rockets“can operate along with us.”

There is a lot of moneyat stake.Airlines say their average cost of “
Excellent Missoni Woven Platform Mules High Quality Shop For Sale Online Pay With Visa Cheap Online Cheap Sale Shop MarFsrH9
,” the industry metric for the period when an aircraft is taxiing or flying, was $68.48 per minute in 2017, or $4,109 hourly, led by crew and jet fuel expenses. The averagedelayof those 563 flights on Feb. 6was 8 minutes. For perspective,100 flights delayed by 10 minutes costs about $70,000, ALPAnoted. To make matters worse, the block timeaverage is likely to rise this year—further aggravating airline executives and pilots whenever a SpaceX or United Launch Alliance LLC rocket closes airspace.

“These restrictions have led to extensive and expensive delays to commercial air traffic that are unsustainable,” ALPA said in a white paper released Tuesday.

“We are smart enough to solve this problem.”

The U.S. airlines’ trade group, Airlines for America (A4A), has urged the FAA to “carefully consider the safety and efficiency impacts to the traveling public” in crafting an integration plan, spokeswoman Alison McAfee said in an email. For example,the group expressed “grave concerns” in a June 15 letter to the FAA about a proposed Spaceport Colorado, which would be located at a small airport less than 10 miles southeast of Denver International, the fifth-busiest U.S. airport.

Nicely guided. Being web designer, i desperately need to learn javascript but could not step up forward. Can you help me in learning Javascript? mail me at :
[email protected]

Hi Sanjay,

Can you teach me. Javascript.

am really interested….where do i get your email address

Apparently a lot of the “try it out” sections in the 4th edition beginner javascript is outdated and doesn’t really work any more. The 5th edition works just fine though FYI.

Thanks for building this guide. I came to the end of codecademy and got stuck pretty hard building my site and trying to contribute to github. After diving into the reading materials and doing these end of chapter exercises I can see why.

I am a designer and programming is totally new to me. I started with Codcademy’s Javascript track like you said. They started with the very basics of programming which was something that really really help me understand the core concepts of Javascript. The book you referred further helped me clarify the concepts. I can’t find any words to thank you for taking your time to show beginner like me a path to learn javascript programming. Thank you very much Richard.

Hello Richard, first many thanks for what you are doing it’s absolutely an outstanding work here helping all the community 😀

i would like to have a look at your MongoDB book but the link seems broken. Is there a reason for it?

Hi, I’m following this study guide and I’m at Weeks 5 and 6: Chapter 12 (Dynamic HTML and the W3C Document Object Model). I have the 5th edition of Beginning Javascript and the chapters and some content has changed. I can’t find DHTML in the 5th edition. Anyone know which chapter should I read in the 5th edition?

Hi, i´m a new visitor this site, and i study you´re plan of studies (Javascript Properly), but the link of MongoDB for JavaScript Applications ebook, don´t work. Tks

Hi RIchard,

Now that the 5th edition of Beginning JavaScript is out, maybe you should update your link? I used your link to buy the 4th edition, which I am now returning.

Enjoying your site! Les

Hi,

If you want to learn javascript.. try learning first C language the godfather of all.. when you already have familiarize the basic concepts and syntax then it will be easy for you to learn easily like js..

So,I started following this track almost a month ,and ended up completing the designated 6 weeks in a little over 4 weeks ,here’s what I’ve created: codepen.io/rashidnaushad/pen/VaKMBJ

Do share your views on the code,and ways to help! I’ll start working on the 7th week assignment soon!

How much time would it take to complete the full track assuming that I spend 2-3 hours a day for each course mentioned?

Is it worth doing the intermediate to advanced after the beginner to intermediate

Search portals aggregate results from several search engines into one page. You can find search portals specialized in a product, for example property search portals. Library search portals are also known as discovery interfaces.

A tender portal is a gateway for government suppliers to bid on providing goods and services. Tender portals allow users to search, modify, submit, review and archive data in order to provide a complete online tendering process.

Using online tendering, bidders can do any of the following:

Hosted Web portals gained popularity and a number of companies began offering them as a hosted service. The hosted portal market fundamentally changed the composition of portals. In many ways they served simply as a tool for publishing information instead of the loftier goals of integrating legacy applications or presenting correlated data from distributed databases. The early hosted portal companies such as

or the now defunct InternetPortal.com focused on collaboration and scheduling in addition to the distribution of corporate data. As hosted Web portals have risen in popularity their feature set has grown to include hosted databases, document management, email, discussion forums and more. Hosted portals automatically personalize the content generated from their modules to provide a personalized experience to their users. In this regard they have remained true to the original goals of the earlier corporate Web portals.

Emerging new classes of Internet portals called Cloud Portals are showcasing the power of API (Application Programming Interface) rich software systems leveraging SOA (service-oriented architecture, Web services, and custom data exchange) to accommodate machine to machine interaction creating a more fluid user experience for connecting users spanning multiple domains during a given "session". Cloud portals like
